Computer Organisation and Architecture
In computer engineering , computer architecture is a set of rules and methods that describe the functionality, organization, and implementation of computer systems. Some definitions of architecture define it as describing the capabilities and programming model of a computer but not a particular implementation. The first documented computer architecture was in the correspondence between Charles Babbage and Ada Lovelace , describing the analytical engine. When building the computer Z1 in , Konrad Zuse described in two patent applications for his future projects that machine instructions could be stored in the same storage used for data, i. Johnson and Frederick P. Brooks, Jr. Buchholz, by writing, .
Functional units of a Computer: Functional Units A computer consists of ve functionally independent main parts: input, memory, arithmetic and logic, output, and control units, as shown below. Input Unit Computers accept coded information through input units. The most common input device is the keyboard. Whenever a key is pressed, the corresponding letter or digit is automatically translated into its corresponding binary code and transmitted to the processor. Many other kinds of input devices for human-computer interaction are: touchpad, mouse, joystick, trackball etc. These are often used as graphic input devices in conjunction with displays. Microphones can be used to capture audio input which is then sampled and converted into digital codes for storage and processing.
